With the increased seam length, Goff says there was actually a risk that this ball would be too rough. “Very little changes in those textures can have noticeable aerodynamic effects,” he says. The fact that the Telstar 18 has almost the same drag curve as the Brazuca, with aerodynamic properties changing at about the same speeds, is impressive. “It has to be an engineering and technical challenge,” he says.
The soccer is the world's most popular and widely watched game. Due to increasing technological advancement and demand for performance, the ball manufacturers have been developing new designs progressively. A traditional spherical football made of 32 leather panels stitched together in 1970s has become only 14 synthetic curved panels thermally bonded without stitches ball in 2006 and more recently 8 panels football in 2010. Despite being most popular game in the world, scan data is available on aerodynamic properties of footballs especially Jabulani, Teamgeist and Fevernova balls. The primary objectives of this study were to evaluate aerodynamic performances of these three soccer balls. The aerodynamic forces and moments were measured experimentally for a range of wind speeds. The aerodynamic forces and their non-dimensional coefficients were determined and compared.
Adidas designs every World Cup ball, and on top of being a big seller for them, engineers at the company are constantly a little closer to the perfect ball, Goff says. The ideal soccer ball is a pimple-covered, perfect sphere, its surface just subtly textured enough to keep the airflow around the ball slightly turbulent. Unintuitive as this might sound, the ridges and pimples on the ball make it more aerodynamic, helping the ball to fly through the air more stably.
This time there is no stitching to attach the panels, but they are thermally bonded. This is the interesting part. First, we wanted to see how it performs in the air for a free kick. You will find a decent, predictable trajectory. Although when you are knuckling, the result mainly depends on your skill and the air direction, a ball plays a vital role as well to help your process of a successful knuckle shot.
This miniaturized soccer ball may seem very tiny, measuring just under 6 inches in diameter. While definitely not a legal size for any type of league play, this small ball is ideal for toddlers to start building their basic skills. Utilizing this ball, your child can practice kicking, grabbing, throwing, and grasping which can assist in the development of gross-motor skills. Playing with your child is also a great way to strengthen familial bonds and bolster your little one’s self-confidence.
Despite having so many good reviews from the users, why aren’t we keeping Wilson traditional ball on our list? It is because we strongly think Wilson is specialized in making tennis equipment. On the other hand, this model did not meet our expectation. This model seems too heavy to us, and overall feel was not too good. That is why we are not recommending you to go for this option. But obviously, the final decision is yours. So many people are still buying this 🙂
Please note, there are only 3 sizes available for this model; size 5, size 4, and size 3. So it is crucial that if you are looking for size 2 or size 1, then this is not an option for you. So, choose the right size before buying so that you don’t regret after receiving the purchase. If you are not sure which size means what then click here to read our guideline.
2010 Jabulani Adidas This ball has 8 panels. A special variant was used for the final match, the gold Jo'bulani (picture on the left), which was named after "Jo'burg", a standard South African nickname for Johannesburg, site of the final game. The ball was notable for the controversy it attracted, with players and fans contending that its aerodynamics were unusually unpredictable.
